Abstract
Description
- The present invention relates to a ceiling fan assembly and a method for assembling same, and, more particularly, to such an assembly and method in which the fan blades can be attached to mounting arms for the fan motor relatively easily and quickly using a minimum number of parts.
- Rotating fans that are mounted to the ceilings of homes and businesses are very popular. These types of fans consist of an electric motor mounted to the ceiling and a plurality of angularly-spaced blades. Each blade is mounted to a corresponding mounting arm and the arms are mounted to the casing of the motor. Rotation of the motor casing causes corresponding rotation of the arms, and therefore the blades.
- However, it is difficult and time-consuming to mount the blades to the arms since a relatively large number of fasteners, or the like, are normally used to attach each blade to its corresponding arm. Since there are usually five blades and arms, the labor costs involved in assembling and mounting the complete fan assembly constitute a high percentage of the overall cost of the assembly. This difficulty in assembly is compounded when the blades have to be mounted to arms that are already attached to the motor casing mounted to the ceiling since it is difficult to make the connections between the blades and their arms in an elevated position.
- Therefore, what is needed is a fan assembly and a method of assembling same in which the fan blades can be easily and quickly attached to the arms, and the arms can be easily and quickly attached to the rotor end casing of the fan motor, without the use of numerous fasteners, or the like, and even when the end casing is mounted to the ceiling.
- An embodiment of the present invention, accordingly, is directed to a ceiling fan assembly and method for assembling same according to which a mounting arm is provided and at least one clamping member extends from the arm. A blade has a portion engaging the arm and a through opening for receiving the clamping member. The clamping member is movable to and from a clamping position to clamp the blade to the arm.
- Several advantages result from this arrangement. For example, the use of a multitude of fasteners, such as nuts, bolts and screws, to connect each blade to its corresponding arm are eliminated. Thus, the fan assembly can be assembled and mounted relatively easily and quickly thus reducing labor costs.

-
- Fig. 1 of the drawings depicts the fan assembly of an embodiment of the present invention which assembly is referred to, in general, by the
reference numeral 10 and which includes ahousing 12 connected to a ceiling of a building by amounting rod 14. It is understood that themounting rod 14 is connected to the ceiling in any known manner, and that electrical conductors extend from an electrical box (not shown) mounted to the ceiling, through the rod, and into the interior of thehousing 12. A conventional electrical motor is provided in thehousing 12 that includes a stator (not shown) and a rotor that includes anend casing 16 that protrudes downwardly, as viewed in Fig. 1, through an opening in the lower surface of the housing. - Five mounting arms, one of which is shown by the
reference numeral 20, are mounted to theend casing 16. This mounting can be in any conventional manner, or in the manners disclosed in patent applications serial No. 097,623, serial No. 196,798 serial No. 243,253, or serial No. 334,976. These applications are assigned to the assignee of the present invention and their respective disclosures are incorporated by reference. - Five elongated blades, one of which is shown by the
reference numeral 22, are respectively mounted to the arms, including thearm 20. The manner in which theblades 22 are attached to thearms 20 will be described in detail. - Referring to Fig. 2, the
arm 20 includes an intermediate portion 20a that extends between a relatively wide blade-receivingportion 20b and a mounting flange (Fig. 1) that connects to theend casing 16 in any conventional manner or in the manners disclosed in the above applications. The blade-receivingportion 20b is tapered in shape and is formed integrally with the intermediate portion 20a. - A
post 24 and threeguide pins arm portion 20b and are preferably formed integrally therewith. Thepost 24 has two parallel grooves 24a, one of which is shown, formed in diametrically opposite walls thereof for reasons to be explained. - A
clamping member 28 is pivotally mounted to the upper end portion of thepost 24. To this end, ashaft 30 extends through a bore formed through thepost 24 and each end of the shaft protrudes from the corresponding outer surfaces of the post. Two flanges 28a, one of which is shown, extend from the lower portions of the respective side walls of theclamping member 28 and each flange has a through opening for receiving the corresponding end portion of theshaft 30. - The lower surface of an end portion of the
blade 22 extends over the upper surface of thearm portion 20b as viewed in Fig. 2. Threeopenings 20b, 20c and 20d are formed though the latter blade portion for receiving theguide pins blade 22 for receiving thepost 24 and theclamping member 28, with a portion of thepost 24, including the grooves 24a, extending above the upper surface of the blade. - A
locking plate 34 extends over the upper surface of theblade 22 and has a through opening 34a through which theclamping member 28 and thepost 24 extend. The opening 34a has a relatively wide portion and a relatively narrow portion having a width substantially corresponding to the width of that portion of thepost 24 in which the grooves 24a are formed, for reasons to be described. - To mount the
blade 22 on the upper surface of thearm 20 the blade is lowered from its position of Fig. 2 with theopenings corresponding guide pins clamping member 28 in alignment with the blade opening 22a. When the lower surface of theblade 22 engages the upper surface of thearm 20, thelocking plate 34 is placed over the upper surface of the blade with theclamping member 28 and thepost 24 extending through the relatively wide portion of its opening 34a. Theplate 34 is then slid in a direction towards the end of theblade 22 shown in Fig. 2 until the relatively narrow portion of its opening 34a extends in the grooves 24a of thepost 24 which locks the blade to thearm 20, as shown in Fig. 3. Theclamping member 28 is then pivoted from its upright position of Fig. 2, shown by the phantom lines in Fig. 3, to a horizontal, clamping position shown by the solid lines in Fig. 3. The design is such that during this pivotal movement of theclamping member 28, the ends of the flanges 28a engage theplate 34 and exert a downwardly directed force against the plate, and therefore theblade 22, to clamp the plate to the blade, and the blade to thearm 20. - It is understood that the other four blades are connected to their respective arms in the same manner.
- As a result of the foregoing, each
blade 22 can be connected to thearms 20 using no fasteners and only theplate 34 and clampingmember 28. Thus, the use of a large number of nuts, bolts and screws is eliminated. Since, thearms 20 can be easily and quickly be connected to theend casing 16 in the manner disclosed in the above applications, theentire fan assembly 10 can be installed relatively easily and quickly thus considerably reducing the labor costs. - It is understood that variations may be made in the foregoing without departing from the scope of the invention. For example, the number of
arms 20,blades 22, andguide pins 26 can be varied within the scope of the invention. Further, the spatial references, such as "upper", "lower", "downwardly", etc., are for the purpose of illustration only and do not limit the spacial orientation or location of the structure described. - It is understood that other modifications, changes and substitutions are intended in the foregoing disclosure and in some instances some features of the invention will be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
